PATENT OFFICE AND WILHELM B. BB-ONANDEB, OF MONT- CLAIR, NEW JERSEY, ASSIGNORS TO SCANDIA MANUFACTURING COMPANY, OF NEWARK, NEW JERSEY, A CORPORATION OF NEW JERSEY CLOTH-FINISHING MACHINE Application filed December 21, 1927. Serial No. 241,510.

i is suitable for the trade.

In finishing silk suitable treating liquids is rubbed into the material and in order to obtain satisfactory results it is very essential that the proper amount of liquid be fed to the material being treated and that the rate of feeding of the liquid to the material be coordinated with the rate of feed of the material through the machine. v

This invention has for its salient ob ect to provide a machine so constructed and arranged that it will remove from textile material, such as silks, all marks, blemishes and disfigurements.

Another ob ect of the invention is to? provide a machine of the character specified so constructed and arranged that the rate of feed of the treating liquid to the material will beproperly coordinated with the rate of feed of the material so that the proper amount of liquid will be fed to the material underall conditions of operation of the machine.

Another object of the invention is to provide in a machine of the character specified means for independently adjusting the speed of the drive for the treating liquid applying mechanism whereby the rate of application of the liquid to the goo'ds'treated can be regulated in a manner best suited to the material treated.

Further objects of the invention will appear from the following specification taken in connection with the drawings, which form a part of this application, and in which of the machine shown in Fig. 1

The invention briefly described consists chiefly in the mechanism for applying the treating liquid to the rubbing element. The machine on which the mechanism is mounted has a supply roll, a take up roll, a table across which the material is drawn, and rubbing elements for burnishing or polishing the material as it is drawn across the table. The treating liquid is applied to one or more of the rubbing elements and the mechanismfor applying the treating liquid is so operatively connected to the power shaft that the rate of speed of the liquid applying roller will be properly coordinated with the rate of take up of the material on the take up roll or the rate of feed of the material through the machine. Since certain materials can be fed throughthe machine faster than. other materials, a variable. speed drive is provided whereby the rate of feed of the material throughthe machine can be varied. However, the connections'between the drive shaft and the liquid applying mechanism and be tween the drive shaft and the take up roll are so coordinated that as the material is fed through the machine at a faster rate of speed the liquid applying roll will operate ata faster rate of speed and vice versa. It has been found that certain materials require at all times properly coordinated with the rate of feeding of the liquid to the material, or to the rubbing element, by means of which the liquid is rubbed into the material. Further details of. the invention will appear from the following description.

In the particular embodiment of the invention illustrated, the machine comprises a frame having tables 11 and 12, preferably formed of glass or like material, and rubbing elements adapted to rub the material against the hard tables. Any desired number of sets of rubbing elements may be utilized and the machine shown in the drawings has two sets of rubbing elements A and B. The material is mounted on a supply roll 15 and is led therefrom over an idler roller 16 across the tables 11 and 12, around an idler roller 17 around a positively driven roller 18 to a take up roller 19 having a shaft or trunnions 20 mounted in slots 21 in the pockets 22, one of which is shown. p

Any desired form of rubbing device may be used but in the embodiment of the invention shown each of the rubbing devices comprises a pair of rapidly rotating belts 25 and 26 of absorbent material, such as felt. The belts are mounted on relatively large, positively driven rollers 30 and relatively small idler rollers 31, the rollers 30 being positioned above the tabes ll and 12. The rollers 31 are carried at one end by yokes 32 having central portions '33 threaded on a screw 34 mounted in suitable bearings and adapted to be rotated to vertically adjust the yokes 32 so as to give the proper tension to the belts 25 and 26. The other ends of the roller shafts are mounted in bearing boxes 35 vertically ad'ustable on screws 36.

he rollers 30 may be driven in any suitable manner and in the form of the invention shown each roller shaft has mounted thereon a worm gear 40 which meshes with a worm 41 carried by a shaft 42. A motor M is connected to the shaft 42 and drives the worm 41, which in turn drives the worm gears 40, It will be noted that the belts 25 and 26 ofeach set of rubbing devices are driven in opposite directions.

The mechanism for applying liquid comprises a pair of rollers and 51 operatively connected by intermeshing gears 52 and 53 at each end thereof. The teeth of the gears 52 and 53 are sufficiently long to permit a slight adjustment of the rollers toward and away from each other. 'The shaft 54 of the roller 50 is mounted in arms 55 adjustably clamped on bearings 56 for the shaft 57 of the roller 51.

The roller 50 can thus be moved toward or away from the belt 25.

The shaft 54 of the roller 50 also has its ends mounted in bearing blocks 60 slidably mounted in guideways 61 formed in the ends of the arms 55, and a spring 62 presses each bearing block 60 in a direction to press the roller 50 against the roller 51.

The roller 50 dips into a tray or receptacle 65 of suitable treating liquid and the liquid is carried around by the roller 51 to the roller 50 and is deposited by the roller 50 on the rubbing belt 25.

Driving connections Referring particularly to Figs. 4 and 5, the machine is provided with a power shaft driven by a sprocket and chain connection 66, 67, 68 from a shaft 69 of one of the rollers 30 of set B of the rubbing devices. The shaft 70 has a variable speed drivin connection G with a shaft 71. Any desired form of variable speed driving connection may be used and in Figs. 4'and 5 there is shown a connection comprising a plurality of gears 72, 73, 74 etc., loosely mounted on the shaft 70 and adapted tobe connected thereto by means of a sliding key 76. The gears 72, 73, 74, etc., mesh with corresponding gears 82, 83, 84, etc., fastened to the shaft 71. Each of the gears 72, 7 3, 74, etc., has an internal keyway formed therein adapted to be engaged by the slidable key 76 and to be thereby connected to the power shaft 70. In Jiigs. 4 and 5 the drive is taken from the shaft 70 to the shaft 71 through intermeshing gears 74, 84.

The key 76, which connected the shaft 70 to one of the gears 72, 73 or 74, is carried by a rod 85 slidably mounted in the shaft 70 and having a pin and slot connection 91 to an arm 92 pivoted on a bracket 93. The arm 92 is connected to a link 94 which in turn is connected to a lever 95 having a slidable catch 96 adapted to engage one of the teeth 97 in a segment 98 mounted on the frame 10.

From the foregoing description it will be clear that the speed of rotation of the shaft 1 can be regulated by ttCl]USt1I1g the lever 95 which in turn controls the adjustment of the slidable key and thus determines which pair of gears will connect the drive from the shaft 70 to the shaft 71.

Shaft 71 has mounted thereon a sprocket 100 which is connected by a chain 101 to a sprocket 102 carried by the shaft 103 on which the roller 18 is mounted.

The other end of the shaft 71 has secured thereto a disk 105 which frictionally engages a roller 106 carried by a sleeve 107 slidably mounted on and keyed to a shaft 108. A yoke 110 is rotatably mounted on the sleeve 107 and is pivotally connected to a lever 111 pivoted at 112 to the frame 10. A locking pawl 115 Is carried by the upper end of the lever and is adapted to engage a toothed segment or rack 116 carried b the machine frame in order to hold the lever 111 in adjusted position. As the lever is swung about its pivot the roller 106 w1ll be moved toward or away from the center of rotation carried by a bracket 121 secured to the machine frame and at its opposite end is mounted in a bracket 122 also connected to the frame of the machine. The upper end of the shaft has mounted thereon a Worm 125 which meshes with a worm gear 126 secured to an extension of the shaft 57 of the roller 51.

The disk 105 is slidably keyed to the shaft 71 and is pressed by a spring 128 into driving engagement with the roller 1063.

Operation of the cZroi ng connections Before the machine is started up and having in mind the material to be treated, the lever 111 is adjusted in a manner to rotate the shaft 108 and, through the driving connections described, the roller 51 at the desired speed to cause the required and proper amount of treating liquid to be deposited on the material. This adjustment is made only once for any one piece of goods.

The operator will then so adjust the drive through the variable speed driving connection C that the material to be treated will be fed through the machine at the proper rate of speed. The machine will then be started, thus feeding the material through the machine and feeding the treating liquid to the material through the belt 25. If at any time during the operation of the machine the operator desires to change the rate of feed of the material through the machine, he will make the necessary change in the variable speed drive C by means of the lever 95, but since the shaft 71 is connected to drive the roller 18 and thus the take up roll 19, which frictionally engages the roller 18 and also is connected to drive the liquid applying mechanism, the rate of drive of the liquid applying mechanism will always hear a definite relation to the rate of drive of the take up roll. In other words, as the rate of feed of the material through the machine is increased, the rate of feeding the liquid to the material will also be increased, and vice versa. It will be obvious that this should be so in order to feed the same amount of liquid or a uniform amount of liquid to the material.

In the modification of the invention shown in Fig. 6, an adjustment screw 130 engages the bearing block to provide a minute or micrometer adjustment of the roller 50.

From the foregoing description it will be seen that a simple, practical machine has been designed for accomplishing the objects set forth and that by the use of this machine the required amount of treating liquid will be fedto the material under all conditions of operation} of the machine and under varying conditions of passage of the material through the machine. As the material is speeded up in its passage through the machine the liquid applying mechanism will likewise be speeded up in order to insure the supply of a uniform amount of liquid to the material.

Although certain specific embodiments of the invention have been particularly shown and described, it will be understood that the invention is capable of modification and that changes in the construction and in'the arrangement ofthe various cooperating parts may be made without departing from the spirit or scope of the invention, as expressed in the followingclaims.
